Be it known that I, HARRY N. DAY, a citizen of the United States vof Americmand a resident of Roanoke, county of Roanoke, State of irgnna, have invented certainnew' 1.1: and useful Improvements in Combined J ack' Trucks and Stands, ofivhich thefollowing IS a clear-and full specification, reference bein had to theaccompanying drawings, in

10 whic p Figure l is a side elevation with the base block elevated; Fig. 2 a'plan View. partly broken away; and, F ig. 3-a'detail perspective view otthe latching devices. I

I The object of this invention is'tofprovide' a' combined truck and stand for heavylifting jacks, such as are used inra-ilroad shops,

repair yards etc., for lifting cars, locomotives, etc); and theinvention consists of cer-' tain novel features of constructionherein after described and articularly pointed out in the claims appended.

The letter a designates the base which may be made of .wood or. metal and maybe I .of any convenient size and shape to accom modate jacks of various makes and ca acity. Bolted to the upper fiat face of the base is ajack 6 of any suitable make, the base being rovided with a central hole 0 to permit the '30 ifting bar todescend into the base. A

transverse vertical slot d extends entirely through thebase at a point; betweenits upper and lower faces, and through this slot extends an axle e on the outer projecting ends of which are mounted transporting 'wheels f..

The axle has free vertical play in the slot and it is uided in its vertica movements by a pair 0 vertical .rods 9 mounted inthe t base and passing through the 'slot. By

means of bol h the ends of a pair of bars arev ivotally attached 'to the opposite sides.

of t e base, and these arms extend rearwardly over the projecting ends of the axle .andare bent toward each other at their rear 3 extremities and are attachedtogetherand Y to a suitable tongue or handle 1'. Pivbta1ly (lependin from the rear extremities of the oonne'cte arms i. is a link In which when the arms are thrown down to the position shown in Fig. 1 is adapted to automaticallyengage under a 'rearwa'rdly extendinghook-Z bolted} to the rear end of the base. a

When the base is to be'lifted off the ground forthe purpose of transportation,-

the handle or lever; j, is. swung downwardly, which act brings into actionthe lever function of the .side bars iand raises-the base from the floor, the projecting 'ends of the axle serving asfulcra for the'levcrs. The base is lifted'until the bottom of the slot 1 strikes against the-axle,at,which point the link It willslip underthe hook l andt thus lock .the parts-in that "position and enable.

, By the use of my apparatus it will be ob:-

served that the. base of the jack is greatly enlarged," therefore :reducing to a minimum .the possibility of. cars being tipped over and "injuring the cars and the workmen, and it 'will be observed also that there.is a large savingof time in movingthe jacks from' place toplace. Also that the'jack is ready to be operated as soon. as it is placedlunder the car to bev raised, the building offounda- '9 tions with: loose blocks, .wedges etc. being- .avoided." -It'.-wi l l be furthernotedthat by H providing the base with the'hole 0 to permit the lowerend of the stem or lift-ing bar to )ass downinto thebase, the lifting stems or ars may be made longer than usual thereby increasin the; liftin "height sixor eight inches; t 'will be f 'rther noted'that my apparatus isfsimple and inexpensive in' con;

struction; and possesses theihighest degree of 9 durability an 'pract-icability it being especially 'highly useful where heavy jacks are The further-advantage is that the lifeof the jackis greatly increased-by the useof 9 my truck.
